Bleh - I'm normally really good about finding it in the documentation. I Just missed that one example when I was looking through it. Thanks for adding the alternate way using Item and MapAt.

@István No I don't mind. It's a good note, but as you say usually not ideal.

@Kuba Oh, that answer? I probably just assumed you were smoking crack. ;^) Seriously if that works now you should post a new answer to the question I just linked in the comment above.

@Kuba Why don't you add mention of that to your answer? The poor computational complexity of MapAt is a long-known problem. This enhancement is going to significantly extend the practical applications of MapAt.
